I leave my chameleon in his free range 24\7 and i have yet to see him venture away from his territorry(im sure this will change when he wants company from a female in his maturing ages), i dont use a mist king yet but my room for some reason keeps a 70 percent humidity consistanly with a spray bottle(if im gone for more than a few days my roomate will mist the tree for me)..my cham stay well hydraited(his casque stays buldged up and eyes stay big and bright, never has issues with shedding)..as for the water under the tree i have plastic layed down over the carpet, and then on top of that some cheap self adhesive tiles layed down..works pretty well, drys it self off, and i wipe it down with a light cleaner once a week..
